Using dovecot with RoundCubeMail - where is the information for new mail in (blue coloured) directories?

People,

Every few years I try to work this problem out - occasionally I would like to re-mark a dir as having new mail so that the dir shows up as blue-coloured in RCM. Every time I Google in vain and then have a go at working it out myself but the only thing I can see is that there is a change in the appropriate dir dovecot.index.log file after having the blue dir clicked on (and the colour of the dir name changes back to black) - so is the information stored somewhere in RCM itself?

Thanks,

Phil.
